Question

2 parallel tangents are drawn at the 2 ends of a diameter .If the the radius of circle is 4cm then find the length of the tangent​

Answer 1

Two parallel tangents are drawn at end of the diameter..

hence, the distance between two tangent is a length of diameter

thus,d=2r

d= 2×4

d=8 cm

Answer 2

The distance between both parallel is equal to the diameter of circle .because both parallel tangent are at opposite to each other and present at opposite side of circle.

so ,4 × 2 = 8
